The aim of this study was to obtain geometric data of patellar ligament (PL) and anterior cruciate ligament (ACL) by MRI and to analyze the correlation of the two with body weight, height and gender. mm and 1.151.09 in males and 42.030.94 mm, 36.001.06 mm and 1.180.1 in females, respectively. In individuals aged 25C64 years, the ideals in males were 40.994.45 mm, 36.063.74 mm and 1.140.09 and in females were 39.840.64 mm, 36.500.81 mm and 1.110.02, respectively. In individuals aged 65 years, the ideals in males were 41.433.08 mm, 36.623.44 mm and 1.150.09 and in females were 38.940.79 mm, 34.360.85 mm and 1.130.07, respectively. There was a significant difference between PL and ACL size on the same part (P<0.01). The data acquired was stable and repeatable. The present study founded a database of PL and ACL size and the percentage of the two measured by MRI. instability. Reconstruction should take place within 3 months, but if it is not then osteoarthritis may occur after 4C6 weeks, resulting in joint alternative and a poor quality of life. Therefore, it is important to diagnose and treat the injury early. Due to the poor self-healing of the ACL, it requires restoration by allograft reconstruction, instead of a simple ACL suture. The KBTBD7 autologous transplantation is currently the most widely used in medical practice and achieves good medical results. Using an arthroscope, ACL reconstruction using the central third patellar ligament (PL) is just about the standard surgical treatment of ACL injury (3). Autologous cells, including the and the muscles, are used to reconstruct the ACL; however, these cells are not sufficiently strong and relax over time. Therefore, the prospective efficacy is definitely poor. In these medical methods, the ligament-tendon insertion is definitely reconstructed into the bone; however, the connection of tendon to bone is not reliable, as it becomes loose or avulses. In ACL recovery using the central third PL, bone-patellar tendon-bone (B-P-B) reconstruction allows bone-bone direct healing. The tensile strength of B-P-B is definitely significantly higher than that of additional tissues and the bones on both sides of B-P-B provide fixed points of the reconstructed cruciate ligament. The medical process achieves bone bio-fixation and is regarded as 1245319-54-3 manufacture the best option for orthopedists with the obvious advantages of security, convenience and high strength (4). In medical practice, a number of factors may lead to surgery failure, including the shortness, injury or pathological changes of the PL, as well as fractures in the operative field or meniscus and articular cartilage injury. A graft that is too long without adequate fixation may cause graft-tunnel mismatch (5C8); consequently, the geometric data of the ligaments directly impact the graft and reconstruction (8). Magnetic resonance imaging (MRI) provides good tissue resolution and high spatial resolution, which allows the obvious imaging of bones, including the patella, femur and tibia, as well as the ligamental constructions of the patellar tendon and ACL, having a obvious boundary from peripheral cells. Demanding data may be from MRI images using an MRI workstation having a precision of 0.01 mm. This is helpful for obtaining geometric data and determining the state of the and ligament of the affected limb prior to surgery. At present, the samples examined in studies of ACL size measurement have primarily been adult cadaver specimens and the ideals reported differ greatly. The Physical Investigation Committee of the Chinese Society for Anatomical Technology provided only data for ACL size (9) and earlier MRI studies were case reports of irregular PL (10C13), which are not useful for ACL restoration surgery. The present study establishes the geometric data of PL and 1245319-54-3 manufacture ACL and provides valuable imaging info for ACL reconstruction. Materials and methods Inclusion criteria of images Clear MRI images of the PL and ACL were obtained throughout the whole process with undamaged continuity. There were low-band signals in sequences and faults of PL. The ACL dietary fiber bundles experienced distinctly visible dietary fiber directions and equivalent signals, while 1245319-54-3 manufacture the dense fiber bundles offered low signals. Enrollment of subjects A total of 157 instances with PL and ACL images were enrolled from October 2004 to March 2007. All individuals were Han Chinese with bilateral MRI results. There were 79 male instances, aged 15C71 years, having a mean body weight of 64.244.98 kg and height of 169.636.06 cm and 1245319-54-3 manufacture 78 female cases, aged 15C73 years, having a mean.
